What's lost is found again: 'Virtually' rebuilding Native American monuments

For five years now, a University of Cincinnati team has been piecing together the fragments of three little-known, prehistoric Native American cultures that left behind immense earthworks that rival Stonehenge in their astronomical accuracy. Most of these sites ? an extant example being Serpent Mound in Adams County, Ohio ? survived close to two millennia before they were gouged out or cultivated in the 19th century or paved over for development in the 20th century. And that’s where the extensive, national team, led by architect John Hancock of the Center for the Reconstruction of Historic Sites at UC, comes in.
